Overview
The Lortsybab KB-621 is a standard stroller for babies, rated to hold up to 33 pounds and built with a polyester fabric over a 21.1 pound frame. Its footprint runs 31 x 14.2 x 42 inches and it is not compatible with a car seat.
At 21.1 pounds this sits heavier than a typical umbrella stroller, which usually buys sturdier construction and more storage in exchange for a bulkier fold, though the exact tradeoff depends on features not listed here such as basket size or recline positions.
- Weight capacity: 33 pounds
- Item weight: 21.1 pounds
- Material: polyester
- Dimensions: 31L x 14.2W x 42H inches
Who it's for
Parents wanting a standard, everyday stroller for a baby up to 33 pounds who do not need a car seat to click in. Less suited to parents wanting a newborn travel system or a light, quick fold travel stroller given the heavier frame.
